Mutuals historically have grande net fees vs ETFs. Good quality index ETFs will come in at the sub 0.10% fee (or $10 per $10,000 invested). Fidelity teams with Blackrock to offer like 500+ Blackrock ETFs with no transaction fees (plus Fidelity has its own small number of ETFs). Come to think of it, I think Fidelity may have offered a couple of index Mutuals with a zero fee recently. Assuming you have no bias (I wont own GOOG, TWTR or FB), you can run with IVV (SP500), or ITOT (Total US Market) for like 0.03%, or if you dont want the GOOG, FB, AMZN crowd FTEC (pure tech similiar but not quite the same as the XLK) fee is 0.08%.
